Abstract:Partial reduction of MeSiCl3 and Me2SiCl2 using CaH2 or (TiH2)n at high temperature (300°C) leads to MeSiHCl2 and Me2SiHCl, respectively, in good yields but in low proportion. In the presence of AlCl3 as catalyst the reaction affords Me2SiCl2 and Me3SiCl, in yields higher than those previously observed in the absence of a reducing agent. These redistribution reactions involve MeSiHCl2 and Me2SiHCl as intermediates. Consequently Me2SiHCl with or without Me2SiCl2 and Alcl3 deposited on carbon black as catalyst can undergo disproportionation to give Me3SiCl.
